Title: Rare earth permanent magnet and method for manufacturing the same
Inventor: KASAI ICHIKAZU
IPC: H01F1/08
Filed: 1978-03-23
Abstract: PURPOSE: To prevent the oxidation and improve the durability, by increasing the binder ratio at the outer surface of the rare earth magnet than in the inner part thereof.  
     CONSTITUTION: Ferromagnetic powder of an intermetallic compound formed from a rare earth element and an iron-family transition element (such as samarium-cobalt) is provided by high-frequency induction heating and ball mill grinding. Then a binder consisting of epoxy-resin having a viscosity of 200W10000 centipoise or the like is kneaded into this by an amount of 4% by weight, and the substance thus obtained   is subjected to compression molding (1.5W7 t/cm 2 ) in a magnetic field of 10000 Oe. Next, the molded article is heated at 150°C for 1 hour to be hardened, and then magnetized to form a rare earth magnet. When the compression molding is effected at a pressure of more than 1.5 t/cm 2 , the binder moves to the outer surface of the article to make the surface binder concetration large, so that the oxidation is prevented and the durability can be improved. Alternatively, the binder concentration at the surface can also be increased by immersing the molded article into the binder and then increasing or decreasing the pressure.

Title: Vacuum treatment apparatus
Inventor: YAMAMOTO HIDEYUKI
IPC: H01L21/31
Filed: 1989-02-15
Abstract: PURPOSE:To reduce dust particles produced during a vacuum treatment by a method wherein an electrode used to apply a cleaning voltage is installed at a vacuum container, a power supply for cleaning use is connected to the electrode and a means to introduce a gas for cleaning treatment use into the vacuum container is provided. CONSTITUTION:One part of a cleaning-treatment gas which has been introduced into a bell jar 20 is evacuated by an operation of a vacuum pump 50; the inside of the bell jar 20 is adjusted to a prescribed cleaning-treatment pressure. When an electrode 80 used to apply a cleaning voltage is turned on, a high-frequency power supply 70 starts operating; a high-frequency voltage at prescribed electric power is applied to the electrode 80 used to apply the cleaning voltage. As a result, a glow discharge is generated between the electrode 80 used to apply the cleaning voltage and a ground electrode 40; the cleaning-treatment gas inside the bell jar 20 is transformed into a plasma; a reaction product deposited on an inside face of the bell jar 20 is removed by utilizing the plasma. Thereby, dust particles produced during a vacuum treatment can be reduced.

Title: Wavelength selecting element
Inventor: KISHIDA SHIYUNJI
IPC: G02B6/293
Filed: 1982-03-02
Abstract: PURPOSE:To obtain superior wavelength selecting performance by forming a gap which slants slightly in the center of a light convergent lens and forming on the gap, a vapor-deposited film for increasing reflectivity to wavelength in  use, and thus forming the light convergent lens and an etalon in one body. CONSTITUTION:At the reflection end 3 of the light convergent lens 1, the vapor- deposited film with high reflectivity is formed and in the center, the parallel gap 5 which has a small slanting angle theta and an interval (d) of size corresponding to the wavelength to be selected is provided. This gap 5 is polished and the vapor- deposited film with high reflectivity to the wavelength in use is formed to obtain functions of the etalon. Because of the slanting angle theta, reflected light with large band width is guided out of a resonator effectively to obtain a narrow band. Consequently, the light convergent lens and etalon are formed in one body and even when the sectional area of an incident beam is small and parallelism is inferior, superior wavelength selecting performance is obtained.

Title: Image pickup device
Inventor: NISHIZAWA AKIHITO
IPC: H04N5/343
Filed: 1990-02-16
Abstract: PURPOSE:To display a picture with a correct aspect ratio at reproduction by inserting a system identification signal representing a video signal in accordance with a 2nd system to part of the video signal when the video signal of the 2nd system is picked up. CONSTITUTION:A pilot signal generating circuit 5 generates a prescribed pilot signal in response to the setting of a switch 11 of an aspect changeover circuit 4 and superimposes the pilot signal between a 10th horizontal scanning line and a 21st horizontal scanning line and between a 273rd horizontal scanning line and a 284th horizontal scanning line for a vertical blanking period of a luminance signal by means of an adder 10. Thus, the aspect ratio at pickup is discriminated by using a system identification signal superimposed for the blanking period even when the signal readout speed of the image pickup element is selected so as to cope with both the current NTSC system (1st system) and a wide pattern television system (2nd system) by means of one image pickup device. Thus, the picture with a correct aspect ratio is displayed.

Abstract: PURPOSE:To prevent the infinite increase in the metric value of the add, compare, select (ACS) circuit of a viterbi decoder by driving a complementary number generated by the output of a selector on the basis of the metric value which is >=1 clock before and performing normal arithmetic. CONSTITUTION:The metric value and the Hamming distance of an input signal are summed up by full adders 1a and 1b, whose outputs are compared with each other by a comparator 2 to select a smaller one in the compared values by a selector 3. The selected output is supplied to an adder 5 and also supplied to a complement generating circuit 10. The complement generating circuit 10 generates a complementary number for subtraction for preventing an infinite increase in metric value, and the number is applied to a D type flip-flop 11 for reclocking. This D type flip-flop 11 holds a complementary number for subtraction for a period of >=1 clock, and the complementary number which is generated >=1 clock before is applied to the adder 5 together with the output of the selector 3. The adder 5 sums up the applied values immediately to determine one metric value through a register 6.

Abstract: PURPOSE:To enhance workability and efficiency by providing a fixed holding portion which engages both the main body of a receiving recessed portion for receiving the lower half of a resin pipe and one side portion of a pipe joint, and also providing a movable holding portion comprising an actuating lever, a torque mechanism and a pushing member. CONSTITUTION:To fit one side flange portion S1 of a saddle S below the bar 41 of a fixed holder 35 and cover the upper half of a pipe P with the flange portion S1, the actuating lever 43 of a movable holder 37 is held in its release position: Then the actuating lever 43 is rotated counterclockwise about a first fixed pivot 45 and then a first and second link arms 67, 71 are rotated counterclockwise about a third fixed pivot 73 and the first link arm 67 is rotated about a fourth moving pivot 69. As the actuating lever 43 rotates, the first, fourth and second pivots 45, 69, 65 pass through a point (dead point) at which they align on a straight line and, as the lever 43 further rotates, the straight line connecting the pivots together is shifted to the left side of the dead point. A pushing force with which the actuating lever 43 tends to rotate counterclockwise is given to a pushing member 75, which in turn strongly pushes the flange S1 of the saddle S downward.

Title: Manufacture of mis semiconductor device
Inventor: TAKANORI TAKESHI
IPC: H01L29/78
Filed: 1986-02-18
Abstract: PURPOSE:To improve the characteristics of an MIS semiconductor device by disposing separating distances of a source electrode, a drain electrode and a gate electrode substantially equal to the thickness of a gate insulating film, and forming the gate insulating film at the initial step of the manufacturing steps to reduce the size and to stabilize the threshold voltage of the device. CONSTITUTION:Only a silicon oxide film 16 disposed on a gate insulating film is selectively removed to expose a gate insulating film 20. Then, an impurity of a polycrystalline silicon film 18 is diffused in a silicon substrate 1 by heat treating to form a source region 21 and a drain region 22. At this time, the entire or partial time of the diffusing step is performed in an oxidative atmosphere to convert the exposed surface of the film 18 into a silicon oxide film 23. The thickness of the film 23 is controlled by the time of diffusing and the diffusing temperature in the atmosphere to be reduced to that equivalent to the gate insulating film. Then, the film 23 is selectively removed to form a contact window.
